Since the interplanetary space is almost vacume, sound can not travel as it need some medium to transfer from one place to another. But electromagnetic wave is present close to all heavenly bodies which emmit at same wavelengths as audible sound (20 to 20,000 Hz) capable of human hearing.

Various NASA instruments, such as Voyager I and II, INJUN 1, ISEE 1 and HAWKEYE space probe, recorded electromagnetic waves close to many planets and their moons and send those signals back to Earth. These instruments used plasma wave antenna to record vibration in audible 20 to 20,000 Hz range. These electromagnetic waves are produced due to complex interaction of charged electromagnetic particles from Solar wind, ionosphere and planetary magnetosphere. These sounds from various space crafts are translated into sounds we can hear. In this video you can listen some of the sample of sounds made by solar system planets such as Jupiter, Saturn, Uranus, Neptune and their Moons.

All of we know the name of the famous scientist Otto Hahn. 8th March is his happy birthday. He was born on 8th March in 1879 and died on 28th July in 1968.

The famous German chemist was a pioneer in the fields of radiochemistry and radioactivity. In 1945 the Royal Swedish Academy of Sciences announced that Otto Hahn had been awarded the 1944Nobel Prize in Chemistry for his discovery of the nuclear fission of heavy nuclei. In 1946 he served as a president of the Kaiser Wilhelm Society and from 1948 to 1960 he was the president of Max PlanckSociety.
